Adafruit BME688 Temperature, Humidity, Air Pressure and Gas Sensor, STEMMA QT, 5046
- Technical high performance – the BME688 from Bosch offers you precise measurements of temperature, humidity, air pressure and VOC gases in a compact sensor. Ideal for your next projects!
- Easy to use – we have placed the sensor module on a board with a 3.3 V controller and level shifting, so you can easily use it with your 3.3 V or 5 V microcontroller.
- Versatile applications: discover the possibilities for air quality measurement and Odor analysis thanks to the integrated MOX sensor, which allows you to detect volatile organic compounds (VOCs).
- Worry-free installation – use our Stemma QT connectors for an easy plug-and-play connection, without soldering. This makes starting with the sensor child's play
- Comprehensive tutorials – In our detailed tutorial you will find everything you need - from examples and code for Arduino and CircuitPython to wiring diagrams and wiring diagrams.

The long-awaited BME688 from Bosch offers you all the environmental sensor functions in one small package. The sensor measures temperature, humidity, air pressure and VOC gases - all via SPI or I2C and at a great price!
The BME688 is a direct replacement for the BME680 and also has a programmable gas heater for odour-based analysis. You can find more details about programming for odour detection in our EYE ON NPI article.
Similar to the BME280, this sensor measures humidity with an accuracy of ±3%, air pressure with ±1 hPa and temperature with ±1.0˚C. Thanks to the precise pressure measurement, you can even use it as an altimeter with ±1 metre accuracy.
The special feature of the BME688 is the MOX sensor, which changes its resistance based on volatile organic compounds (VOC) in the air. So it can detect gases and alcohols such as ethanol or carbon monoxide. Note that it gives you a general VOC value, but does not distinguish individual gases.
To use the sensor, I recommend letting it burn for 48 hours to stabilise sensitive changes and then operate in the desired mode for 30 minutes when used again.
On the board we have integrated a 3.3 V controller and level shifter for you. You can easily use it with your 3.3 V or 5 V microcontroller. All pins are available on 2.54mm headers. And thanks to the Stemma QT connectors, this can even be done without soldering!
